session in url when created<

[liunx]

I'm using sessions on my site and whenever a session is created (the first time someone visits my site) the session id is displayed in the url. Once the person goes to a different page on my site it isn't display in the url anymore. It doesn't matter which page the session is creating in, it always happens. I've tried some htaccess things but none of it worked. Any ideas on how to fix this?I believe it is a setting in the php.ini file.
